look up any word, like fapchat:
Something that is so hot it will give someone a boner merely by their eyes' reception of photons that are either reflected off of it or in some other way represent it. Colloquially used to describe particularly attractive women. Use to describe men is less common.
Subject A: Yo dawg, dat bitch HOTT!
Subject B: Yeah dude, that's some visual viagra right thurr.
